Shared ground
Jeremiah 38:19–20 portrays a king who knows what the prophet is saying but cannot act because he is afraid. Zedekiah’s fear is concrete: Judeans who already defected to Babylon might betray him and publicly shame him. The text presents fear of human backlash as a major driver of political and spiritual paralysis.
Jeremiah answers at the level of that fear. He directly denies the king’s predicted outcome (“they will not hand you over”) and then ties the path forward to “obey the voice of Yahweh” as Jeremiah is delivering it. The passage also links obedience with two stated outcomes: the king’s well-being and the preservation of his life.
Where interpretation differs
Two questions sometimes get read differently.
First, who are “the Jews who have fallen away to the Chaldeans”? Some read this as a narrower group (defectors with influence, possibly connected to leadership or military), while others take it more broadly as any Judeans who already surrendered. The verse itself only specifies “defectors,” not their social rank.
Second, Jeremiah’s assurance (“They shall not deliver you”) is taken in two main ways: either as an absolute promise regardless of circumstances, or as reassurance meant to operate within Jeremiah’s urged course of action (the obedience/surrender he has been pressing in the larger scene).
Why the disagreement exists
The immediate wording in v. 20 gives both an assurance and a plea to obey, without spelling out the exact logical connection (“they will not deliver you” because you obey, or “they will not deliver you” and therefore obey). Also, the phrase “obey the voice of Yahweh, in that which I speak to you” assumes knowledge of Jeremiah’s earlier, more specific instructions in the surrounding narrative.
What this passage clearly contributes
Explicitly, it shows (1) fear of humiliation and betrayal shaping Zedekiah’s choices, (2) Jeremiah confronting that fear with a specific counter-claim, and (3) prophetic speech presenting obedience to Yahweh’s message as the practical route to survival and “well-being.” Theologically inferred (but consistent with the scene) is that rejecting Yahweh’s word can be motivated less by intellectual doubt than by fear of people, and that Jeremiah frames Yahweh’s instruction as life-preserving, not merely condemning.
